  • MULTICOMPONENT LAYERED DIELECTRIC FILM WITH SURFACE MODIFICATION
    Publication number: 20210291499
    Abstract: A multicomponent dielectric film includes overlapping dielectric layers and outer layers that have a higher surface energy compared to the overlapping dielectric layers, the overlapping dielectric layers including at least a first polymer material, a second polymer material, and optionally a third polymer material, adjoining dielectric layers defining a generally planar interface therebetween which lies generally in an x-y plane of an x-y-z coordinate system, the interfaces between the layers delocalizing the charge build up in the layers.

  • MULTICOMPONENT STRUCTURES WITH IMPROVED MECHANICAL PERFORMANCE
    Publication number: 20210252829
    Abstract: A multicomponent structure includes a substrate having a plurality of fiber-like reinforcement materials embedded in a matrix material. The reinforcement materials have a rectangular cross-section defined in part by the matrix material and extend a length of the multicomponent structure. In one embodiment, the multicomponent structure includes at least one recyclate.

  • Composite shape memory materials
    Patent number: 11014341
    Abstract: A multilayered composite shape memory material includes a coextruded first polymer layer of a first polymer material and a second polymer layer of a second polymer material. The composite shape memory material after thermomechanical programming being capable of undergoing at least one temperature induced shape transition from a temporary shape to a permanent shape. The first polymer layer defines a hard segment of the shape memory material that provides the shape memory material with the permanent shape, and the second polymer layer defines a switching segment of the shape memory material that provides the shape memory material with the temporary shape.
